长吻飞旋海豚的一些生物学测量数据

Some measurements of the spinner dolphin Stenella longirostris

2003年11月山东省石岛的渔民在黄海水域偶然误捕了一头海豚,经作者鉴定,系长吻飞旋海豚(Stenella longirostris),国家Ⅱ级重点保护动物,是黄海水域的首次记录。其主要鉴别特征:喙细长;背鳍略呈三角形;尾柄很高,具有结缔组织构成扩大的嵴;齿数:右上颌47枚,右下颌50枚,左上颌47枚,左下颌51枚。同时,还对其进行了较详细的观察和测量:此海豚系雄性,体长1.828 m。为长吻飞旋海豚的保护以及管理措施的制定提供了基本的参考资料。
